SPECIEEGATION fomoing mlrt of Letters Patent No. 667,558, dated February 5, 1901. Application first 0mm 22; con. serial No. 33,834. on model.

To all whom it may conccrm. Be it known that I, EDWARD MCJOHN, acitizen of the United States, residing at Newark, in the county of Essex and State of New Jersoy, have invented certain new and useful Improvements in Bicycle-Locks and Ido hereby declare the following to be a full,clear, and exact description of the invention, such as will being had to the accompanying drawings, and

to-letters of reference marked thereon, which form a part of this specification.

The objects of this invention are to provide lock for bicycles which shall prevent the 'peararce, and efficiency, and to obtain other the description of the working parts.

The invention consists in the improved bicycle-lock herein described and in the arrangenients and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses I transverse sections, 7 lines y and z of Fig. i.

tion illustrating the use of 45 ot the same on line'zc, Fig

0f the claim.

Referring to the accompanying drawings, in which like letters of reference indicate cor responding parrsin each of the several views Figure 1 shows in side view a portion of a bicycle with my improved look as applied thereto after the bioycle'is completed. Fig. 2 is a front view of the same; and Fig. 3 isa transverse sectiomon an enlarged scale, taken through line as, Fig. 2. Fig. iis a front view showing the look as appliedto a bicycle in building. Figs. 5 and 6 are iongitndinal and respectively, taken on Fig. Tshows the key Fig. 8 i.s a side elevaa certain washer hereinafter described; and 9 is a section 8 I for operating the look.

In said drawings, a indicates the inclined sleeve at the front ofe bicycle, which receives the post I) of the fOI'kjQBfiid post being turned freelyinsaid sleeve by the handle-bars fc to steer the bicycle. To the outer surface of said slee ein carrying out my invention 1 apeiergotsttoos.

ply a projecting block d, ofmetal, which forms lateral arms 9, adapted to clasp around the to a completed bicycle by providing it with sleeve and be clamped together at their ends by a bolt or screw g. In applying in the course of manufacture of the bicycle,

thin projecting edges it formed on the block to lie in the aperture, as illustrated in Figs. .d'to 7;

In this latter construction the aperture h and base of the block are of an ang-ularshap,preferablydiamond-shaped, to prevent turning.

The central socket d" of the block d is threaded, and the correspondingly-threaded lock-holt'e works therein, said lock-bolt passing through the wall of the sleeve a and at its innerextrernity either abnttingagainst the rotary post I) or entering a recess 12 therein, according to the relative position of post and sleeve. The recess is so located that when the ficient friction of the lock-bolt in its threaded the like; j The inclosing cap is, above re 9O socket to prevent-its, movement by jarring or f screwed or otherwise secured at its open end to the seat'k, provided at the front ofthe block (3, the said cap inclosing and surrounding the lock-bolt, as shown. the cap 7c is centrally perforated, as at Land a flange l projectsinward from around said cylindrical The outer end of ferred to, "is

of the lock-bolt the flange i of the bolt engages the flange Z of the cap and the unlocking of the bolt is limited. The head of the lock boltflt will be observed, is never exposed beyond the cap la. In use, therefore, of my imprtrzed lock the rider when he dismounts to leave his bicycle clamps the lock-bolt c firmly against the post I) or into the recess therein. In this condition the post b, fork b, and frontwheel m, cannot be turned to steer the bicycle, and hence it is impossible to ride the bicycle, and it can be stolen only by being carried off bodily.

In the construction to which I have referred as applicable to bicycles in building it may under some conditions be desirable to secure greater strength by the means illustrated in Figs. 8 and H. Here a washer n is applied to the outside of the tubular sleeve a, said washer passing loosely over the front end or seat Ir. of the block (1 and being suitably curved or shaped at its inner surface to lie against the sleeve 0, around the edges of the aperture h. The cap 7t is then screwed onto the part tightly against the washer n,thereby gripping the edges 71 around the aperture h firmly between the flange 71, of the block on the inside and the washer n on the outside.

The outer face of-the washer n preferably is flat, and the cap 7; may have a rim 7; engaging said face of the washer.

Having thus. described the invention, what I claim as new is- 1. The combination with a bicycle having the apertured sleeve (1 and post 19', therein, of the block cl, having a head or flange held in l the aperture and a portion It, projecting outside the slecve, and being perforated at right angles to the sleeve and intcriorly threaded, a lock-bolt t, extcriorly threaded and working in the said perforation of the block and adapted to be screwed against the outer surface of the post I), to clamp the same against. turning in the sleeve, a cap 70, secured to the projecting portion is, of the block and inclosing the end of the lock-bolt and having a keyhole in line therewitlnand a flange on the lockbolt adapted to close said keyhole when the parts are in unlocked position, substantially set forth.

2. The combination with a bicycle having the sleeve u, and postb', of a block (Z, secured l to said sleeve and havingan interiorly-screwthreaded perforation at right; angles to the, post and opening at its inner end against the, post, a lockbolt correspondingly threaded to l screw in said perforated block and be thus clamped against the post I), at any point of a threaded lock-bolt working its circumference, a' cap or lock-ease inelosing the outer end of the lock-bolt and having a key-opening in line therewith, and an annular flange on the lock-bolt back from its key-receiving end and adapted to cover the key-opening when the bolt is unscrewed from the post I), and close said key-opening against dust and the like while the bicycle is running, substantially as set forth.

The combination with a: bicycle having the sleeve (1,, and post 1:, of a block (l, fixed to said sleeve and having a threaded socket,

and adapted to engage at its inner end the post, the outer cnd'of said bolt having a pe' righeral llauge and an angular head, a cap It, secured to the block (I, and inclosing the lock bolt, said cap being apcrtured at its outer end in a-lincinent with the lockdaolt, and having an interior stop limiting outward movement of the. lock-bolt, and a key adapted to be, inserted through the z'tperture in the cap and clutch the head of the lock-bolt, substantially as set forth. i I

t. The combination in a bicycle, of the apertured sleeve a, the perforated block r7, having a head or flange lying in the sleeve and a portion in, projecting through the aperture, a washer it, placed over said projecting portion of the block and adapted to lie against the outer surface of the sleeve, a screw-bolt 6, working in the perforated block (7, and a hollow cap is, screwed upon the projecting end 7c, of the block (1, against the washer n, at its inner end and at its outer end limiting outward movement of the bolt and having a key-aperture providing access to the saidbolt, substantially as set forth.

5. In a bicycle, the combination with the sleeve (1,, and post 0', turning therein, of a block (L secured to the sleeve and providing a threaded socket, a lock'bolt re, screwing in said socket and adapted to engage at its inner end the post I), the outer end of said bolt hav ing a flange or stop, and a hollow cap seen red to the block (I, and inclosing the outer end of the lock-bolt,.and at its outer end being perforated and having a rec-ntrant tubular keypassage engaging at its inner end the llange or stop on the lock-bolt, substantially as set forth.

In testimony that 1 claim the foregoing l have hereunto set my hand this lilth day of October, 1900.
